I took some longer exposures of Omega Centauri last night 10 minutes each with my Baarder Skyglow filter and WO II RF atatched but there appears no blue channel On a DPP histogram of a numebr of frames, is this natural for this object or was this the effect of the Skyglow filter or is it jsut me and the blue can be adjusted via curves when stacked and processed in PS
The blue is there but way off to the right on the histogram as to appear no too be there
